I have one of the only seats that can keep a 5-pt harness up to like 85 pounds or something. Problem is, I just read on the side of the seat that the LATCH is only good up to 50 lbs, and I need to now use the seatbelt to secure the seat. Well, Josh is at 51 lbs now. We have to switch it, and we've never used the seatbelts to secure the seat.

We have the carseat book somewhere. I really like the idea that they're all still in 5pt harnesses. I'm sure once we have to take his friends from place to place it'll become reallllly uncool but I don't care.

What I'll need to find is the actual book from our car (which is probably in the glove bo about LATCH and confirm that 50 lbs is the limit for them.

It's true. Most manufacturers require that you discontinue LATCH use and start using the belts at weights over 40 pounds (sometimes 48, sometimes 50). The reason is that the Latch anchors can deform in a severe accident with a heavier child, thereby making him susceptible to injury. Obviously, the seat belt webbing isn't going to deform catastrophically like a piece of metal will when put under force.

If you've never used the belt to secure the seat, it's pretty easy. As long as your car isn't ancient, it should have an automatic locking retractor (ALR) belt. What that means is that when you pull the belt all the way out to its limit, it will start ratcheting as it retracts. So basically put the belt through the area designated for forward facing belt installation, fasten the belt, then pull the retractible end of the belt all the way out. While pressing on the seat as hard as you can, let as much of the belt as possible retract. I usually plant my knee in the seat and put as much of my weight in as possible while grabbing the slack end of the belt and pulling it tight.

It should be fine. A lot of times you can get a better installation with the belt, believe it or not!
